+	  device based on the CoreChip-sz SR9800 chip.
+
+	  This driver makes the adapter appear as a normal Ethernet interface,
+	  typically on eth0, if it is the only ethernet device, or perhaps on
+	  eth1, if you have a PCI or ISA ethernet card installed.
+
+	  To compile this driver as a module, choose M here: the
